We've been battling green water in our 10G freshwater tank for a couple of months. Finally got a UV filter and it did wonders! Now my question to you folks that have UV filters, do you run it all the time or only when there's an issue?
I would have to get a timer, lol. I'm terrible at timing.The green machine recommends 8hrs a day. So in one of my tanks it’s on a timer the other is 24/7 because I keep meaning to put it on a timer .
